Effectiveness of Alternate-Day Fasting for Weight Loss

Alternate-day fasting (ADF) involves eating about 25% of usual calories every other day and may support weight loss, improve metabolic health, and potentially promote longevity, though results vary and it isn't suitable for everyone. Key benefits include fat loss, metabolic switching, and cellular repair, but quality of food on feast days matters. Certain groups like pregnant women, children, and those with eating disorders should avoid ADF. Consulting a healthcare provider before starting is recommended.
